Abstract: An objective of the present invention is to reduce the downtime which occurs when changing a servo motor device. A servo motor device includes a motor section and a reduction gear configured to output a driving force by reducing a speed of rotation of the motor section, wherein a control device includes a detecting section configured to acquire detected information about operation of the motor section, and a computing section configured to generate an approximate curve based on a behavior for a time sequence of a parameter and to calculate predicted lifetime information of the servo motor device based on the approximate curve thus generated, wherein the parameter has been calculated by means of the detected information.

Abstract: The present invention provides a main body with a coupling section, wherein the circuit board includes terminals for power supply and for signal, wherein the coupling section has a first positioning section and a second positioning section, and wherein the assembly is configured so that in a state where positioning has been performed by the first positioning section, positioning by the second positioning section is performed and the coupling section is coupled to another coupling section of another main body. Thus, coupling the coupling section is performed in the state where positioning has been performed, wherein connection of the terminals for power supply and for signal to power supply and signal terminal sections is performed in this state, which may enable the operability for coupling a coupling section to be improved while ensuring a mechanically and electrically correct coupled state.
